.. you don't seem to have noticed: individually imported models are written in italic.
True. I had not noticed. But then, I do not think I have checked adding imported model to the catalogue... Too busy adding Furniture Library information 
But it is a nice touch, and probably solves part of the problem for most users. It is that sort of function I would like - only on a library level. Anyway, it was just a thought. Mostly me kicking myself for not using tag/information etc better so I can find a way in my own mess. ok
